Gibraltar SWN10-11BP-G Threaded Ball Plunger 4-48

Product Description

The GIBRALTAR SWN10-11BP-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a zinc-plated steel body with a nylon ball, providing corrosion resistance and smooth, non-marring contact on mating surfaces. The 4-48 threaded body measures 0.187 inches in length with a ball diameter of 0.062 inches and a maximum ball reach of 0.02 inches. An integrated locking element secures the plunger in place once installed. Initial end force is 0.13 pounds, rising to a final end force of 0.5 pounds, making it suitable for low-force detent applications in precision equipment and fixture work.

This ball plunger is used in light mechanical assemblies where repeatable positioning or soft detent feedback is required. Typical applications include jig and fixture construction, tool-and-die work, instrument panels, and small machine components. The nylon ball minimizes surface damage on softer mating materials, while the zinc-plated steel body holds up in general shop and industrial environments. It is installed and serviced by machinists, tool makers, and mechanical assembly technicians working with 4-48 threaded bores.

Key Features

• 4-48 thread size for use in fine-threaded bores in small mechanical assemblies
• Nylon ball provides non-marring, low-friction contact on mating surfaces
• Zinc-plated steel body offers corrosion resistance in general industrial environments
• Integrated locking element prevents loosening from vibration or repeated cycling
• Low initial end force of 0.13 pounds with 0.5 pound final end force for light detent applications
• Compact body length of 0.187 inches suits confined installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation component for mechanical assemblies requiring a 4-48 threaded ball plunger with a nylon ball and steel body.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a screwdriver or hex key appropriate for the plunger head style. Ensure the mating threaded bore is clean and free of debris before threading in the plunger. The locking element engages as the plunger is tightened to the desired depth — do not overtighten, as this can damage the nylon ball or the threaded bore. De-energize or mechanically lock any powered equipment before servicing assemblies containing this component.
